Will Pausing Propecia (Finasteride) for Three Weeks Cause Catch-Up Hair Loss?Tue 10 Jan 2017
I have been taking Propecia for 18 months with no side effects. Recently I had a blood test that showed my testosterone was 1141, which is high. I need to stop now for three weeks to repeat the test and I am really concerned my hair will fall out within the three weeks. As soon as I get my results I want to start back at a half dose or maybe even 1mg.
My question is: Will I lose all my hair I gained over the last year in 3 weeks and will the hair stop falling again when I start back?
Taking a 3 week break from Propecia (finasteride) won’t necessarily result in significant and irreversible “catch up” hair loss. But, it’s important to note that there seems to be a lot of variability in the experiences of individual users. Unfortunately, the only way to find out how your body will respond is by stopping the drug.
That being said, I would not be too worried about this short interval.
